Classification of maintenance techniques and diagnosing failures methods

Abstract

Equipment components essentially the parts responsible for power transmission and bearings will expose to multiple types of stresses, including external stresses coming from the nature of the working and internal stresses resulting from movement between the moving parts or thermal industrial processes. These stresses lead to damage or defect, which adversely affect the current or future performance of these systems. To ensure the reliability of the machine or structure has to establish a continuous condition monitoring system that can detect the abnormal condition state early. This paper will cover the monitoring techniques used to observe the mechanical conditioning of the vital components(such as bearings, shafts, gearboxes, etc.) In an ultra-low frequency rotating machinery in industrial applications including hydroelectric generator, steel mills, paper mills, water sewage plants, cement kilns, and wind turbines.
